IMPROVEMENT IN RUT-LEVELERS.

Specification forming part of Letters Patent No. 110,663, dated January3, 187.1.

To @ZZ whom it may concern:

Be it known that I, CALVIN MARSHALL, of North Easton, in the county ofBristol and State of Massachusetts, have invented a new and usefulBut-Leveler; and I do hereby declare the same to be fully described asfollows, and to be represented in the accompanying drawings.

rIhe purpose of the said machine is to efface the ruts formed in a roadby the wheels of carriages.

Of the drawings,Figure l denotes atop view, Fig. 2 a bottom view, andFig. 3 a longitudinal section, o'f the machine.

In the said figures, A denotes a frame provided with a tongue, B,(pivoted to it at one end,) and also having a roller, C, arranged withinit at or near its middle, such roller being supported so as to be freeto revolve. At the back part of the frame or in rear of the roller thereis a platform. a, furnished with a seat, b, for a person to sit uponwhile the machine may be in use. In advance of the roller the frame isprovided with two metallic scrapers, D D, arranged obliquely in manneras shown in Fig. 2, they being `fastened to projections c c from theframe, and held thereto by clamp-screws cl going through slots e, madein each ofthe Scrapers, such being to admit of the Scrapers beingadjusted or depressed, as circumstances may require, after they maybecome worn. A long lever, E, pivoted to a standard, F, erected on thefront part of the frame, has its front arm extended between two crosspieces or bars, f f, bolted to opposite sides of the prongs g g lof thetongue, the whole being as shown in the drawings. If prefera ble, theScrapers may be connected with the lever, so as to be raised ordepressed directly by it. I prefer, however, to have them fixed to theframe, and the lever pivoted thereto or to a standard, as set forth.

In the operation of this machine a yoke of oxen or draftanimals is to besupposed to be attached to the tongue. The driver, while sitting uponthe seat of the platform, will nearly counterbalance the weight of thefront part of the machine, tending to press the scrapers downward. Bymeans of the lever he can either increase the downward pressure of theScrapers on the road-surface or he can lessen the same or raise thementirely out of contact with such surface, as circumstances may require.The Scrapers serve to scrape up and deposit into a rut the earth on eachside of it, the roller operating to compress the earth into the rut, andto level or smooth the surface of the roadway while the machine may beputin movement over the same.

I am aware of the rut-leveler or scraper described in the United StatesPatent No. 7 ,462, dated June 25, 1850, and granted to Nathaniel Potter,and make no claim thereto, my rutleveler being very different therefrom,both in construction and operation, although there are in the twomachines some common features.

I therefore claim- My improved rut-leveler, as described, consistingofthe roller C, the frame A, the scrapers D D, the tongue B, and thelever E, all arranged and combined as specified and represented, so asto operate or be capable of being actuated in the manner and by themeans as hereinbefore set forth.

CALVIN MARSHALL.
